logilab-common #6592 incorrect edges syntax in dot file generation [resolved]

fix dot files' edge generation

Before this patch, edges were defined using the following scheme :

Node1 -> Node2 edge [attrs...] Node2 -> Node3

which dot understands as three instructions :

Node1 -> Node2 ; edge [attr...]; Node2 -> Node3;

which means that edge properties are applied to the Node2->Node3 edge rather than to the Node1->Node2 edge.

The correct syntax is :

Node1 -> Node2 [attr...]; Node2 -> Node3;
